Concentration

No, we're not talking about the U.S. performance on the final day of the competition. At the start of that final day, Rory McIlroy is seen speeding to the course (video above) in a private car minutes before his match against American golfer Keegan Bradley.

McIlroy made it to Medinah Country Club with just a few minutes to spare before he would have been disqualified for being late.

McIlroy was able to win the match, but it could have been disastrous for the European team if he had been late.

Conditioning

Rory McIlroy is the No. 1 golfer in the world and he keeps himself in good shape and always has followed an exercise regimen.

However, it may not be enough just to maintain his fitness level and work with a physical therapist to stay flexible.

He may need to get stronger as the years go by to counteract any loss of flexibility that may come with time. Tiger Woods certainly added physical strength over the years as he held the No. 1 ranking for many years.

Getting stronger may serve McIlroy well in the years to come. He seems to be paying more attention to this, following the example of his girlfriend Caroline Wozniacki and her physical sport that requires maximum conditioning (source: Golf Digest).

Driving Accuracy

According to his PGA driving stats, McIlroy was fifth in driving distance in 2012, averaging 310.1 yards off the tee. When it comes to hitting a big drive at a key moment, McIlroy is almost certainly the best in the world.

Sometimes when you have that much length, you are going to sacrifice a bit of accuracy. That was the case for McIlroy because he did not always keep his drives on the fairway.
